Solid walls and older backing coats
A great deal of Morden housing was built between the wars with solid walls and cement-based backing coats. After ninety years of fixings, tiles, wallpaper and repairs, those walls are rarely flat. Skimming works well where the backing is sound; where it is blown, the failed sections need cutting out and re-forming first, otherwise the new finish fails with the old.
We check this by sounding the wall before quoting, so the price reflects what the wall actually needs rather than a guess made from the doorway.
